Severe Weather 1/2-in x 4-ft x 8-ft CDX Pressure Treated Douglas Fir Plywood Sheathing

Charlotte Wood Middle School, Danville, California

It was 1991, and our company was framing the entire middle school. The Charlotte Wood Middle School was built out of Douglas Fir Lumber, Pressure Treated Plates, and different kinds of Plywood. I negotiated a contract with a lumber mill in Oregon to provide all the dimensional lumber for the project. I had lumber being delivered from their mill for months. GREAT PROJECT!

Product Features

• Plywood Sheathing

  For both residential and commercial construction, this is the most suited structural building material.They are usually regarded as the best options for wall sheathing due to their general capacity to securely hold fasteners, forge a solid bond between studs, and to offer some thermal benefits.

• Finish for exterior use: For any outdoor project, be sure to properly prime, paint, or seal the lumber to protect it from California's weather.

This Plywood is on the higher end. Why?

• It comes from it being both structural-grade (CDX) and pressure-treated for severe weather.

• Best Uses for Severe Weather CDX Pressure-Treated Plywood.

• Exterior Sheathing in Wet/Damp Conditions

• For walls, roofs, or floors where moisture exposure is likely during construction or long-term.

• Siding or roof sheathing that will later be covered but needs to survive heavy rain before dry-in.

• Used as a base for decking, outdoor benches, or picnic tables that need extra durability.

• Plywood walls or skirting that come close to soil, where untreated plywood would rot fast.
